needs stats and initial cost if you want it to be a creature. i would expect warlock to be in
or
, but since this one presumably just casts elemental blast (not really a warlock spell typically) repeatedly,
is most in theme with the effect. but with ability cost and boni for quanta as is you wouldnt play it in anything but a rainbow or maybe material quad. powerlvl of ability seems comparable to elf (in rainbow converted cost is also the same), though it gets much better with excess quanta and drainlife on a stick bringing both healing and boardcontrol at the same time might make it seriously strong in a stall.
ofc it also doubles as a finisher that ignores most shields as well
